人类为了防洪、发电、灌溉、航运的需要,往往在运河或天然河流上兴建许多水利工程,如闸、坝等。这样便形成了集中落差,给船只过坝(闸)带来了困难,升船机就是解决这个问题的一种主要过船建筑物型式。它的原理是利用水力或机械的传动将船只提升过坝(闸)。升船机的原始形式为干拖船舶的斜面滑道,它在公元前600多年就出现了。随着科技的发展,升船机建造得越来越多,规模也在不断增大。升船机的型式很多,如果按照过坝(闸)方式
For the sake of flood control, power generation, irrigation and shipping, human beings often construct many water conservancy projects such as gates and dams on canals or natural rivers. This created a concentration gap that made it difficult for a ship to cross a dam (gate). Shiplift is one of the major types of over-ship structures that solve this problem. Its principle is to use a hydraulic or mechanical drive to lift the ship across the dam (gate). The original form of the shiplift was a sloping chute of a dry tugboat, which appeared more than 600 years BC. With the development of science and technology, the lift ship is built more and more and the scale is also constantly increasing. There are many types of lift ship, according to dam (brake) way
